Pace Scientific Inc.

Pace Scientific develops and markets portable data loggers and sensors. Pace data loggers are used for facility, environmental and machine monitoring; and for research and remote unattended data logging, with no external power required.
Pace provides free software for use with its dataloggers, available on Windows, Linux, and Mac OS X. Data files are Excel compatible.
Pace data loggers are compatible with over 50 sensors stocked at Pace, and many 3rd party sensors. Sensors include temperature, humidity, pressure, ac and dc current, ac voltage, light, wind speed & direction and rainfall. Accessory cables read dc voltages up to 60 vdc. Pace data loggers accept thermistor, thermocouple and platinum RTD temperature probes. Total system accuracy using a Pace datalogger for temperature monitoring is up to +/-0.15 deg C with no calibration. All sensors are powered from the data logger's user-replaceable batteries. Typical battery life is 2+ years, with any mix of up to 8 sensors.
